Abstract

EL PRESENTE INVENTO SE RELACIONA CON UN DISPOSITIVO PARA PRODUCIR ARTICULOS PLASTICOS DE FORMA HUECA POR MOLDEO DE INYECCION INCLUYENDO EL DISPOSITIVO UNA TOBERA (10) PROVISTA DE UNA PRIMERA ABERTURA DE ENTRADA PARA EL PLASTICO FUNDIDO PROVENIENTE DE LA MAQUINA DE MOLDEO POR INYECCION Y UNA SEGUNDA ABERTURA DE ENTRADA PARA UN GAS, MEDIOS PARA DIRIGIR GAS HACIA EL PLASTICO FUNDIDO Y UNA ABERTURA DE SALIDA A TRAVES DE UNA PUERTA QUE SE PUEDE CONECTAR CON UN ESPACIO DE MOLDEO. LA SEGUNDA ABERTURA DE ENTRADA SE COMUNICA A TRAVES DEL CONDUCTO (28) CON UN ACUMULADOR DE GAS (29) QUE TIENE UN VOLUMEN CONSTANTE Y EN EL QUE EL GAS TIENE UNA PRESION SUBSTANCIALMENTE CONSTANTE. DICHA CONEXION TAMBIEN TIENE UNA MARIPOSA VARIABLE (32) POR MEDIO DE LA CUAL PUEDE AJUSTARSE EL FLUJO DE GAS A TRAVES DEL CONDUCTO.THE PRESENT INVENTION IS RELATED TO A DEVICE FOR PRODUCING HOLLOW PLASTIC ARTICLES BY INJECTION MOLDING, INCLUDING THE DEVICE A NOZZLE (10) PROVIDED WITH A FIRST INLET OPENING FOR THE MELTING PLASTIC FROM A MACHINE AND A MACHINE. INLET FOR A GAS, MEANS TO DIRECT GAS TO THE MOLTEN PLASTIC AND AN OUTLET OPENING THROUGH A DOOR THAT CAN BE CONNECTED WITH A MOLDING SPACE. THE SECOND INLET OPENING IS COMMUNICATED THROUGH THE DUCT (28) WITH A GAS ACCUMULATOR (29) THAT HAS A CONSTANT VOLUME AND IN WHICH GAS HAS A SUBSTANTIALLY CONSTANT PRESSURE. SUCH CONNECTION ALSO HAS A VARIABLE BUTTERFLY (32) BY WHICH THE GAS FLOW THROUGH THE DUCT CAN BE ADJUSTED.
